An increase in ventilation reaching the alveoli that results from an increase in the depth of breathing, the rate of breathing, or both.

Below, under, deficient, containing less than usual.

Decreased pain in response to a normally painful stimulus.

Characterized by less than normal pressure or density. Applies to a solution with lower specific gravity than that of another solution taken as a reference.

As a surface disinfectant, used at the right concentration and pH is effective against most vegetative bacteria, fungi, enveloped and non-enveloped viruses as well as Mycobacterium tuberculosis and bacterial spores if solution remains at high concentration. It is inactivated by organic substances. For sporicidal concentration: 1 part household bleach to 9 parts water; approximately 5,000 ppm free chlorine – good for 24 hours, then need to make fresh again.

Location: promontory of sacrum. Serves pelvic plexus and viscera of pelvis. Contains sympathetic elements.

Underdevelopment undevelopment of a tissue or organ.

A core temperature less than 36C (96.8F).

Body temperatures below 36C or 96.8F, where the physiology of the tissue and at the cellular level is adversely affected including the immune response (resulting in an increased risk of infection), poor clotting, reduced drug clearance and poor quality scar tissue. There are times when hypothermia is intentionally induced locally or systemically, reducing cellular activity such as after a heart attack, stroke, or during heart surgery. This reduces oxygen demand and can be protective of vulnerable tissues near the injury. However, temperature must be brought back to normal levels as soon as possible to avoid the deleterious effects of hypothermia during patient recovery.

A decrease in ventilation reaching the alveoli that results from a decrease in the depth of breathing, the rate of breathing, or both.
